NiCoP/Mo3Se4 Nano-Heterojunction as a Promising Bifunctional Catalyst for Full-Water Splitting under Low Cell Voltage

Graphical Let's split !: A low-cost and high-efficiency NiCoP/Mo 3 Se 4 multifunctional catalyst was reported for highly efficient full water splitting. The abundance interfaces in NiCoP/Mo 3 Se 4 played a great role in optimizing the electronic structure of the nanoheterogeneous to efficient charge transfer. As expected, a low voltage of 1.90 V was needed to drive full water splitting at the current density of 400 mA cm −2 . The simultaneous manipulation of the catalytic activity and intrinsic electrical conductivity in a unified system is difficult yet meaningful to unravel the possible strategy that can enhance the water splitting performance. In this work, a low cost and highly efficient NiCoP/Mo 3 Se 4 nano-heterogeneous bifunctional catalyst was reported for full water splitting. Further analysis revealed the abundance interfaces in NiCoP/Mo 3 Se 4 played a great role in optimizing the electronic structure of the nanoheterogeneous to efficient charge transfer. As expected, a low voltage of 1.90 V was needed to drive full water splitting at the high current density of 400 mA cm −2 .
